Actually, I don't know why but if you can give us the whole API logs maybe we can see the issue there.

And what pool do you mine? Take note if you are mining on Nicehash ASICboost pool even their non ASICboost pool expect for the abnormal status of your miner you should mine on other pool. Canaan gears are mostly do not support Nicehash pool so I suggest you try other pools like ViaBTC, slushpool or kano or you can try any pool from this https://miningpoolstats.stream/bitcoin
